Today's the UNESCO #WorldBookDay! #OpenStreetMap can help you find books.

We map libraries <https://wiki.openstreetmap.org/wiki/Tag:amenity%3Dlibrary> (incl. little free libraries <https://wiki.openstreetmap.org/wiki/Tag:amenity%3Dpublic_bookcase>), and bookshops <https://wiki.openstreetmap.org/wiki/Tag:shop%3Dbooks>.

Several books have been published about #OSM: <https://wiki.openstreetmap.org/wiki/Books>
We want OSM to be used, so if you need a map for your book, we have very generous & liberal attribution requirements: https://osmfoundation.org/wiki/Licence/Attribution_Guidelines (and can show where to buy your stationary https://wiki.openstreetmap.org/wiki/Tag:shop%3Dstationery )
